SPECIFICATION forming part of Letters Patent No. 586,164, dated July 13, 1897. Application filed Qctober 30, 1896- Serial No. 610,527. (No model.)

To all whom it may concern.-

Be it known that I, PETER DENERE, a subject of the King of Norway and Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Floor-Planes, of which the following is a specification.

This invention relates to improvements in a tool to be used for smoothing floors and other irregular and uneven surfaces; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The objects of my invention are, first, to provide a floor planer or scraper which shall be simple and inexpensive in construction, strong, durable, and effective in operation; second, a planer or scraper which by reason of its peculiar construction and the novel arrangement of its parts may be used with either a pushing or pulling stroke, thereby affording a tool which may be employed for scraping or smoothing the surface close to the wall or other structures or projections arising from the surface being planed or scraped, and, third, a planer or scraper in which the plane-bit or scraping-blade may be adjusted either in the front or rear of the stock, so as to limit the depth of cut and prevent splintering by the movement of the tool.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in Which--- Figure 1 is a view in side elevation of my plane or scraper, showing by continuous lines the bit or knife thereof in the position when used with a pushing movement and by dotted lines when used with a pulling movement. Fig. 2 is a longitudinal sectional view taken on line 2 2 of Fig. 3 through the center of the stock, showing the meansfor securing the plane-bit or scraping-knife in position. Fig. 3 is a cross-sectional view taken on line 3 3 of Fig. 1, and Fig. 4 is a detached perspective view of the plane-bit or scraping knife or blade.

Similar letters refer to like parts throughout the different views of the drawings.

A represents the stock or block, which is usually composed of three portions or pieces a a and a secured to ether b 1 means of screw-bolts I), located at proper points transversely in the block or stock. The piece a is located between the pieces a and a and extends upwardly and rearwardly to form a handle A, by means of which the tool is pushed or pulled over the surface to be planed or smoothed. The central lower portion of the piece a is formed with a recess 0, which tapers upwardly to receive the correspondinglyshaped adjusting-block C, employed for adjusting and securing the plane-bit or scraping-bladeD. Extending from the top of the recess 0 through the upper part of the piece a is an opening 0 for the reception of a thumb or set screw 0, which passes into an opening 0 in the block 0 and engages a nut 0 fixed in the adjusting-block, as is clearly shown in Fig. 2 of the drawings.

The pieces a and a are usually formed on their adjacent surfaces and in their lower central portions with recesses a for the accommodation of the sides of the block 0, but said recesses may be omitted when the piece A is of su'fficient thickness to admit of the operation of a block in the recess thereof; but for compactness I prefer to form the pieces a and a with the said recesses. Secured to the lower surface of the pieces a and a, by means of countersunk screws 6, is a metal plate E, which glides over the surface being planed and prevents the wearing of the pieces CL and a, which are usually made of wood. At the front and rear ends of the recesses c and a in the pieces a and a and a", respectively, are oppositely-inclined slots f, which extend from the lower surface of the stock upwardly and toward each other and terminate in circular openings f. These slots are for the reception and retention of the planebit or scraping-blade, which may be placed in the rear one, as shown by continuous lines in Fig. 1 of the drawings, when it is desired to use the plane with a pushing movement, or in the forward one, as shown by dotted lines at cl, when the plane is used with a pulling movement.

The plane-bit D or scraping-knife is made rectangular, as shown in Fig. 4 of the drawings, and may have each of its edges provided witha bevel at, so that each edge may be used for smoothing the floor or other surface by simply changing the position of the bit or blade. Just above the rear portion of the plate E the pieces a and a are cut away or formed with a rearward bevel e, which construction provides an opening or recess between the plane-bit or scraping-knife D and the plate and said pieces for the escape of shavings or particles removed from the flooring or surface being planed or scraped.

By reference to Fig. 1 of the drawings it will be seen that the slot f in the front portion of the block or stock is located near its end, so that when the bit is placed and secured in said slot the floor or surface being scraped can be acted on very close to the wall or other projection. When it is desired to adjust the bit in either of the slots, the set or thumb screw C may be turned so as to force the adj usting-block O downward, which will disengage it from the bit and allow it to be turned or properly placed within the desired slot, when by turning the screw C in the direction to raise the adjusting-block O the said bit or plate will be firmly held in position.

In using my plane or scraper the handle A is grasped with one hand, while the other hand of the operator may rest on the forward portion of the block or stock, when the tool may be forced forward or backward over the floor or surface being planed, as may be desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination with a stock having in its lower portion a tapering recess and an oppositely-inclined transverse slot at each end of the recess, of a block located in said recess and having its ends inclined to correspond with the incline of the slots, a set-screw engaging the block and adapted to adjust the same, and a plate secured to the stock below the recess therein and between the said slots, substantially as described.

PETER DENERE.
